It flaunts a 10 point multi-touch 4 inches WVGA touchscreen display which is set to a decent 480 x 800 pixels resolution. It is encompassed with 8GB of ROM storage and 1GB RAM. The storage of the Zenfone A40CG can be expanded further by 64GB through a MicroSD card.

The display is made from TFT material and it has Corning Gorilla glass protection. Just like Moto E, this phone comes with a rear snapper of a 5MP sensor and a VGA camera at the front for clicking selfies. As it has the hardware to connect with UMTS 3G networks, this device can be used to make video 3G calls. One more impressive feature of Asus A400CG is its battery.

The company claims that the device gives around 12 hours of talk-time and 290+ hours of standby time on 3G UMTS networks. GPS, Glonass and assisted GPS navigation technologies can be leveraged to the full extent through this device. As there isn’t any phone within 5k to 6k Rs with such configuration, we can consider the Asus A40CG the best mobile under 6000 Rs. The device has 2 GSM micro-SIM slots, FM Radio, 11.5 millimeters thickness. It will compete with Xiaomi Redmi 1S which carries the same price tag as the Zenfone 4.

Update: On 11th of Feb, Asus has launched its Zenfone 4 successor with an FWVGA 4.5 inch display, full HD video recording support, and a 2100 mAh battery. This device is named as Zenfone C and it costs around 5999 Rs. Specs of this new phone are not very good. You can buy Karbonn Android One or Arya A1 plus with quad-core CPU for below 5K Rs.
